Apple has sent out an email to developers saying that iTunes Match has updated alongside the release of iTunes 10.5.1 beta 2. The update includes a “number of important stability and performance improvements” and iTunes Match has now been made available for testing on the Apple TV.
Developers that have been using iTunes Match must update to iTunes 10.5.1 beta 2 to continue using the service. Once upgraded, iTunes Match can be enabled on all supported Apple devices. On the Apple TV, select “Music” and then “Turn on iTunes Match.” Your music will then be available for streaming on Apple’s set-top box.
Apple projected the public release of iTunes Match for the “end of October,” and that date has come and gone.
Apple cautions developers to, “Please remember to backup regularly and do not delete the music you add to iCloud from your computer.”
No ETA on a public iTunes Match release has been given at this time.
